Viscosity of partially hydrolyzed polyacrylamide under

For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.

High Viscosity of Partially Hydrolyzed Polyacrylamide

Partially Hydrolyzed Polyacrylamide (PHPA) Polymer Powder PHPA Powder for Drilling Mud Additive Bluwat Chemicals is the leading manufacturer and exporter of good quality PHPA(Partially Hydrolyzed Polyacrylamide) for oil drilling and EOR process. It is a high molecular weight polymer that controls fluid loss and increases viscosity, friction ...

The preparation of high‐viscosity, partially hydrolyzed

Due to the high chain transfer to monomer, the homopolymerization of methacrylamide yields polymers of extremely low molecular weight. On partial alkaline hydrolysis, the viscosities of these polymers in aqueous solution are much inferior to those of partially hydrolyzed polyacrylamide (HPAM).

Viscosity of partially hydrolyzed polyacrylamide under

For oil field applications, partially hydrolyzed polyacryl- amide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.
